Accidents happen very quickly in day to day life. Breaks in-front of you would slam your foot in a fraction of second, along with your body. To overcome this instance an ejector seat has been designed as an idea of improvement with current existing safety tools which protect people when a car crashes. Traditional airbag is limited in that it protects people after car is crashed and in many situations it would be too late, and also it cannot protect people when the car falls off a cliff. The ejector seat ejects people with different weights to the same height when danger is detected.
The prototype results show that it can detect relative distance and speed accurately with a small error of +/-2 cm, and the weight can be measured to an accuracy of +/- 2 grams. The seat is ejected and when relative distance and speed reach a threshold that we calculated to be reasonable for deadly situation, and the springs which are used to eject are compressed to desired position to make sure that different weights are ejected to the same height. This situation is immediately sent to the nearby server helpline through GSM module, and help is availed at once.
